Systems equations not solved

[mhamdi]

A system equation doesn't work, it dislaying the error: no solution found.

I think that this is a placement or pages issue as even the function numbering is not working ( when setting namebers for each paragraphe title, it not exceed 3)

Please find attached the worksheet

The equation system is on page 34

The same equation works in page 11

Its page 10

The symbolic "solve" command does not like it if the variable you want to solve for already was assigned a value. To clear variable C.1 (only for symbolics, it will retain its numeric value) you simply type C.1 := C.1 and the symbolic solve will work.

As you are using units (the symbolics does not know anything about units!) and are looking just for a numeric value, you might consider using a numeric approach. Either using the function "root" or a solve block:

You may also use the "root" with a guess value and without providing a range like 0N to inf N.

You may also use the solve block without a guess value if you evaluate the "Find" command symbolically.

thank you for your explanation, its very clear.

Do you know also why the numbering function doesn't work?

Please see the attached screenshot.

Unfortunately no and as in the meantime you have deleted your worksheet from the first post I can't have a look how you implemented that numbering and what might have gone wrong
